GEORGE A. LUTZ, OE PLAINFIELD, NEW JERSEY.

PRIMARY ELECTRIC BATTERY.

T0 all whom t may concern.'

Be it known Vthat I, GEORGE A. LUTZ, a citizen of the United States, andresident of Plainfield, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Primary ElectricBatteries, of which the following isa specification.

My invention relates to improvements in primary electric batteries, andparticularly tothe class of batteries employing a negative elementcomprising cupric oxid compressed to plate form, and one or more zinesfor the positive element.

'lhe object of my invention is to maintain the positive and negativeelements in proper relation to each other; to preventdanger of saidelements coming into contact with each other; to enable the readyreplacement of the elements when required, and generally to simplify andimprove such class of batteries.

In carrying out my invention I provide a compressed plate of suitablematerial for the negative electrode, and I attach to said plate one ormore positive electrodes by means of suitable insulation, whereby one ofthe electrodes is supported by the other electrode. I also interposebetween the positive and negative electrodes suitable insulation servingto prevent said electrodes from coming in Contact and to maintain itheir relative spaced relation to each other.'

My invention also comprises novel details of improvement that will bemore fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof,wherein,

Figure l is a sectional view of a primary electric battery embodying myinvention substantially on the line l, l, in Fig. 2; Fig. 2 is a sectionsubstantially on the line 2, 2, in Fig. l; Fig. 3 is a detail edge viewof the battery elements; Fig. 4. is a sectional view of a modification;Fig. 5 is a partly broken face view of the battery elements of Fig. l;Fig. 6 is a detail face view of the negative element, and Fig. 7 is anenlarged detail view of part of the elements.

Similar numerals of reference indicate corresponding parts in theseveral views.

The numeral l indicates a negative element or electrode, shown in theform of a circular plate, which may be a well known compressed plate ofcupric oxid.

Application led December 6, 1909. Serial No. 531,485.

At 2 is a frame or band surroundingvelectrode l, and which may be madeof channeled metal receiving the edges of said electrode. I have shownsaid frame as made in two main parts havingears 2a connected together bysuitable means, such as a bolt 3, the opposite ends-of the two parts ofthe frame being suitably cut away at the sides so that therespective endportions 2b may overlap and be attached to a metallic hanger or post 4,as by means of screw 5. The upperend` of post 4L is shown provided witha reduced threaded portion ala providing a shoulder lb to fit againstcover 6 of jar 7, a suitable-nut or binding post 8 fitting upon thethreaded end of post 4 holdingsaid post firmly suspended from cover 6and providing for attachment to a line wire.

One or more positive electrodes or zincs 10 l are supported by andinsulated from electrode l andlocated at a suitabledistance vfrom theside or sides of electrode l. VvFor this purpose I have shown aninsulating block l1 extending transversely through and projecting fromelectrode l, as bypassing through an aperture therein, within whichaperture said block may firmly fit, the electrodes or Zines l0 beingattached to lsaid block, for which purpose I haveshown bolt l2 passing`through bores in zines l0 and block 1l, and electrically connecting thezines. Block 11 is shown provided withreduced end portions 11a, passingthrough corresponding` holes in zines 10 and providing shoulders 1lbagainst which said zines are clamped by bolt 12, thereby serving toelectrically connect said zines and retain said zines in proper positionspaced from electrode l.V To further aid in keeping electrodes 10 spacedfrom electrode 1 and in` proper relation thereto I provide electrode lwith insulating blocks 14 extending outwardly into position for coactionwith electrodes 10. yBlocks let may be carried. by electrode 1 in anysuitable manner. I have shown said blocks as attached to frame For thispurpose I have shown said frame provided with tongues 2c struck from thematerial thereof and folded over or around blocks 14 to hold the latteragainst frame 2, whereby said blocks are securely and detachablyconnected with said frame, and said blocks may be adjusted as required.

In Figs. l, 2 and 3 I have shown insulating blocks 14 as provided withinwardly extending portions 14a coacting with elecv swinging toward gg Y1,161,322

trodes 10 to` prev-ent said electrodes from electrode 1. T he in wardlyextending portions 14a oli' blocks 14,

which may be of any desired length, serve as abutments for saidelectrodes as the latter are eaten away in use, so that if saidvelectrodes become reduced in diameter the insulating extensions 14acontinue to coact withsaid electrodes. r1`he conductor 15 for thepositive electrodes-maybe attached to manner, but preferably by'castingthe metal oit the electrode around the conductor. At 16' 1s aninsulating protector, such as a rubber tube inclosing conductor 15. The

conductorl may be connected with a binding post 17 upon cover 6 in wellknown manner. Instead of providing blocks 14 with 'extensions 14a, I mayprovide electrodes 10 with extensions to-coact'with blocks 14 as shownin Figs. 4' toft. In this case wires 18 are vembedded in electrodes 10so that the A 'ends `18?0 said wiresproject from said electrodes andcoact` with insulating blocks 14,.for Whichpurpose I have shown the-ends`Vof blocks 14 provided with recesses 14b receiving theends 18acitvvire's 18,'Whereby electrodes 10 are kept spaced :trom engagelmentWith elect-rode 1', and as electrodes 10 ldecreasein diameter during usethev wires 18 Vremain in coaction with blocks 14 to keep `electrodes 10properly spaced from elecj trode v1.

il iwfWhile I have illustrated-ak practical embodiment' oi my invention,the same yis not limited to the details and arrangements set forth, aschanges may be made, Within the scope of thel appended claims, withoutdeparting from the 'spirit of my invention.

yI-Iaving 'novv described by invention what I claim is 2- 1. Batteryelements comprising a negative electrode, an insulating block passingthrough and projecting from opposite sides of said electrode, positiveelectrodes carried bythe insulating block on opposite sides of thenegative electrode, aboltV passing through said positive electrodes andinsulationand electrically-uniting said electrodes,

and other insulation interposed between the positive and negativeelectrodes to retain them in position. Y v Y 2. Battery elementscomprising a negative electrode, insulation carried thereby, a positiveelectrode attached to said insulation, and oneor more insulating piecesconnected with said negative electrode and having an extension locatedbetween said electrodes and extending substantially parallel therewith.

3. Battery elements comprising a nega.- tive electrode, an insulatingblock extending on opposite sides thereof, electrodes attached to saidblock, and one or more insulating pieces connected with the negativeelectrode and having extensions extending substantially parallel to saidelectrodes and coacting with the positive electrodes.

y4. Battery elements comprising a depolarizing plate, a frame attachedthereto, an` insulating block carried by said plate, one or moreinsulating pieces carried by said frame, and a positive electrodesupported by and insulated from said plate.
